Manual TECHKON SpectroDens
By measuring the trapping only the variation
from the reference will be displayed.
The ISO standards define no tolerances for
trapping, only informative reference values
are given.
But it is recommended, not to exceed a ∆E*-
value of 10 in the secondary colors, which
corresponds with the sum of the permitted
∆E*-deviations of the primary colors.
Instead of scanning the TECHKON strip the
measurement function ISO-Check can also
capture the ECI/bvdm Gray Control Strip ver-
sion tvi 10 (i1) and (M i1).
When using the scan function we recom-
mend to use a patch width of 5 x 5 mm (min.
4 x 4 mm) with the standard aperture and a
patch width of 4 x 4 mm (min. 3 x 3 mm) with
the exchangeable 1,5 mm aperture.
